Related application

The present application claims the priority of the Chinese Patent Application No. 201 810 203 586, filed on March 13, the entire disclosure of which is hereby incorporated by reference.

Technical field

The present disclosure relates to display technologies, and in particular, to a display position adjustment method, apparatus, and system.

Background technique

Due to technical limitations, the effective viewing angle of most displays is relatively small (ie, the viewing angle is small). When viewing the display, the viewing performer of the display must watch within a certain distance and effective viewing angle, when the display is viewed by the performer. The line of sight falls on the center of the display and is perpendicular to the display surface to get a better viewing effect, otherwise the effect will be poor.

For example, during endoscopic surgery, the surgeon can perform surgery in real time by viewing the internal tissue of the human body imaged on the medical display, which requires high viewing quality and effect.

Instead, the steps depicted in the flowcharts can change the order of execution. Additionally or alternatively, certain steps may be omitted, multiple steps being combined into one step, and/or one step being broken down into multiple steps.

The specific steps in the use are described below:

In the scenario where the viewing performer of the 3D display needs to change the orientation and the 3D viewing quality is high, using the 3D display position adjusting device and method provided by the embodiment of the present disclosure, the initial position debugging is first performed to correct the initial of the 3D display. The height and the distance between the display and the viewing performer of the 3D display, the spherical center of the sphere defined by the contour of the curved bracket coincides with the viewing point of the viewing performer of the 3D display (ie, the viewing distance is the spherical radius R, and the viewing line of sight is viewed) It falls in the center of the screen and is perpendicular to the screen to ensure a better initial viewing. The subsequent 3D display is based on the spherical position adjustment, which makes the adjusted effect consistent with the initial effect.

After booting, first enter the initial process (in the initial process, the 3D display will be adjusted to the initial position, that is, the first connector, the second connector, and the third connector are in a straight line, the plane of the display is the first curved rod and the first The plane of the two curved rods is vertical. The initial process is divided into a height matching and distance matching process. First, the height matching is performed, and then the distance matching is performed. The following is an example of the 3D viewing device of the 3D display.

Highly matched

After the user wears the 3D viewing device, the height sensor on the 3D viewing device measures the height h1 of the 3D viewing device and the ground, and sends it to the 3D display position adjusting device. The height sensor on the curved bracket also collects the curved bracket center in real time. The distance between the position and the ground is h2, the processor compares the heights h1 and h2, and drives the motor in the third connector to drive the first curved rod to move up and down along the support rod. When h1 is greater than h2, The first curved rod moves upwards. When h1 is smaller than h2, the first curved rod moves downward. During the adjustment process, the height sensor can continue to collect the height h2 in real time. When h1 and h2 are equal, the height matching process ends, and the arc ends. The center position of the bracket and the 3D viewing device are at the same vertical height.

Distance matching

After the user wears the 3D viewing device, standing in a fixed position, the line of sight is directed to the 3D display, at which time the distance sensor on the 3D viewing device starts working, measuring the distance between the 3D viewing device and the 3D display L1, the 3D viewing device Sending the L1 value to the 3D display position adjustment device, which compares L1 with a preset spherical radius L2, and when L1 is greater than L2, lights up a yellow light, prompting the user to push the stand toward the 3D viewing device wearer. When L1 is smaller than L2, it lights up red, prompting the user to withdraw the bracket from the 3D viewing device wearer. The distance sensor on the 3D viewing device can work all the time, and the distance information L1 is transmitted to the 3D display position adjusting device. When L1 and L2 are equal in the distance adjustment process, the green light is on, indicating that the distance is appropriate, and the matching process of the distance ends.

Position adjustment during viewing

When the initial process is completed, the viewing can be performed.
